Rubocop: Missing frozen string literal comment

[micpringle]

I recently updated to Rails 5 and was hit by #3273. Today, after updating json and json_pure, I've come across an issue with RuboCop that appears to have been around before. Before the update to Rails 5 I didn't have a single offence in my current codebase, but now there are an absolute ton of them, all related to Missing frozen string literal comment.

Here's the RuboCop output:

[backus]

Add the following to the top of all of those files:

# frozen_string_literal: true

You can just do bundle exec rubocop --auto-correct --only FrozenStringLiteralComment.

or add an ignore to your rubocop.yml if you don't want to use the Style/FrozenStringLiteralComment. It is new because this is a new feature in Ruby 2.3.

[micpringle]

Thanks @backus.

I've gone with adding Style/FrozenStringLiteralComment to my rubocop.yml file for now.

What I don't understand is that this feature has been in RuboCop since 0.36.0, released back in January, and I've been using Ruby 2.3.0p0 with this codebase since it was created, but these issues only appeared this week after a) upgrading to the official release of Rails 5 from RC2, and b) upgrading RuboCop from 0.36.0 to 0.41?

[scottmatthewman]

Is it possible that the change in Ruby version handling, e.g., in #2956, triggered the change in behaviour, @micpringle?

[micpringle]

It may well be the cause @scottmatthewman, as I do use a .ruby-version file. Thanks for pointing out that issue. 👍

[backus]

@micpringle happy to help. I was reading through related issues before I opened #3285. If your problem is solved could you close this issue? I imagine the rubocop maintainers will appreciate that

[gnapse]

I would try with one of these two possible solutions:
